[Were they honestly comparing notes, they might find they have a lot in common. Brian understands all too well how it builds, like a spring winding too tight, slow at first (when it hasn't been too long) but excruciating as time goes by.
For now, he has his game to keep him grounded, but that's not what he wants when push comes to shove. He's not hunting. He'd much rather be, but there are too many reasons it's impractical. But he is out late, stalking the streets quietly, because he's got too much energy to keep himself penned in anymore, because he's going to start snapping soon and he needs that not to happen.
He's doing little more than pacing, taking streets at random with quiet and confident strides. If they're going to call it killing time, it ought to be more satisfying.]
